DESIGN SIZE – Actual dimension SWD and LWD.
Measured from a point to a corresponding point on the adjacent diamond.
SWO – Short Way of Opening.
LWO – Long Way of Opening.
STRANDS – The sides of the Expanded Metal design.
STRAND THICKNESS – Thickness of the base metal.
STRAND WIDTH – Amount of metal fed under dies to produce one strand.
STRAND THICKNESS AND WIDTH – Can be varied to create different openings. The width of the strand should equal or exceed the thickness of the base metal.
Diamonds – Open area of metal after expanding. Most Expanded Metal patterns are diamond shaped but may also be hexagonal, louvered, asymmetric,etc.
Edge Configuration – Condition of the edge of an Expanded Metal sheet. Usually refers to "open" (random) or “closed” (bond) diamond edges produced from shearing.
